Summary of the bug:
All versions of compiled ffmpeg 5.0 on Ubuntu 20.04 now produce a segfault
on completion of any file using hevc_nvenc encode. This does not happen
in any ffmpeg version before version 5.0.
Used release 5.0, then updated to release N-106467-ge301a24fa1. Same
issue. Have to revert to a compiled version of 4.4.1 to avoid this error.
Commands plus gdb and valgrind output are below. The problem seems to be
between ffmpeg/hevc_nvenc and the nvidia drivers. Sample ffmpeg log
output is attached.
